Filed: 1988-11-14
Abstract: PURPOSE:To check whether a system is normally working as designed or not even though the system is kept under its designing state by checking whether the input data is accordant or not with the process conditions defined by the defining data and reporting this checking result. CONSTITUTION:A defining data input means 1 inputs the defining data to define the processing contents and the processing conditions in response to a word name for execution of a system designing job. Thus the input defining data is successively stored in a defining data storage means 2. A check means 3 reads the defining data out of the means 2 in response to a check command. Then the means 3 checks whether the data inputted for check is accordant or not with the processing conditions defined by the defining data as long as the read defining data is equal to an input word showing at least the input of data. Then an error if detected is reported via a report means 4. Thus it is possible to check whether a system is normally working as designed or not even though the system is kept under its designing state.

Abstract: PURPOSE:To prevent the flux density at a detecting part from fluctuating due to the fluctuation of gap between the detecting part and the surface of a steel plate and the gap between a magnetizer and the surface of steel plate, and to prevent the saturation of a signal when a high sensitivity detector is employed. CONSTITUTION:A magnetic detector 23 is loaded to a magnetizer 11 through a vertical moving mechanism 14 and a horizontal scanning mechanism 15 and then the vertical moving mechanism 15 operated to sustain a constant gap between the magnetic detector 23 and a steel plate 22.
